In-Vehicle Communication Device

1. A communication device that is provided in a vehicle and is configured to communicate with an external center, the communication device comprising: a processor and memory programmed to: collect data to be transmitted to the center; transmit the data to the center; predict an occurrence of communication interruption between the center and the communication device based on predetermined information and stop transmitting the data in a case where the communication device predicts that a predicted time from a current time to the occurrence of communication interruption is less than a first predetermined time, predict a resolution of communication interruption between the center and the communication device based on information for specifying whether or not communication with the center is possible, and in a case where it is determined that a predicted time from a current time to the resolution of communication interruption is less than a second predetermined time while the communication device stops transmitting the data, the communication device is programmed to resume transmitting the data; and collect at least high-priority data while the communication device stops transmitting the data and when transmitting the data is resumed, the communication device is programmed to transmit the collected high-priority data.

2. The communication device according to claim 1 , wherein the processor is configured to, in a case where the processor predicts that communication interruption occurs within the first predetermined time, cause the processor to transmit high-priority data among pieces of data collected before the communication device stops transmitting the data.

3. The communication device according to claim 1 , wherein the predetermined information includes information indicating a preset traveling route and information indicating whether or not communication is possible at each point within a predetermined range around the vehicle.

4. The communication device according to claim 1 , wherein the predetermined information includes a steering angle of a steering wheel and information indicating whether or not communication is possible at each point within a predetermined range around the vehicle.
